Black bear human-wildlife conflict during hyperphagia

Black bear activity is increasing near human settlements across several regions in North America due to hyperphagia, a seasonal period where bears consume massive amounts of calories to prepare for winter hibernation.

In early October, reports emerged from Coahuila, Mexico, and North Carolina, USA. In Coahuila, bears have been observed attempting to access food through cabin windows. In North Carolina, wildlife authorities issued alerts noting that bird feeders, pet food, and unsecured trash are attracting bears to residential areas in counties such as Buncombe, Haywood, and Henderson.

By late October, similar patterns were reported in Oregon and Michigan. In Western Oregon, a shortage of mountain berries has driven bears toward human food sources earlier than expected. In Michigan, increased sightings have been noted in Marquette, Gogebic, and Iron counties as bears forage for acorns and berries. In both states, wildlife experts are advising residents to use bear-resistant containers and secure all food sources to prevent bears from associating humans with easy meals.
